Description
Technical field
The invention belongs to technical field of polymer materials, relate to the method for a kind of melt drawing production high strength, high modulus polyethylene filament.The polyethylene filament that this method is produced can be widely used in numerous areas such as mining industry, building materials, rope, as hawser, boats and ships ocean engineering hawser, climbing rope, fishnet, racing boat, sailing boat, bowstring, ski, mine safety protection network, various screen cloth, enhancing shock resistance container etc., also can do the building trade reinforcing material, and replace glass fibre or the like.
Background technology
Ultra-high molecular weight polyethylene (is called for short: UHMWPE), it is the very excellent thermoplastic engineering plastic of a kind of combination property, its production process is similar to high density polyethylene (HDPE) with molecular shape, all be to adopt Ziegler catalyst to form branching linear molecule chain seldom through coordination polymerization, its difference is the length of strand, i.e. the size of molecular weight.The molecular weight of common high density polyethylene (HDPE) is generally several ten thousand to hundreds of thousands, and the molecular weight of synthetic ultra-high molecular weight polyethylene surpasses 1,500,000 under certain condition, even reaches 10,000,000.Strand just because of ultra-high molecular weight polyethylene is long especially, so it is good especially to have physical mechanical and chemical property, the especially ABRASION RESISTANCE of many uniquenesses, ranks first in known plastic.
High molecular weight has been given it and has been had common polythene and other engineering plastics unrivaled special performances: have superpower ABRASION RESISTANCE (be iron and steel 8-9 doubly, 4 times of nylon, 27 times of brass); Excellent in impact resistance (being 2 times of Merlon, 5 times of ABS, 15 times of polyformaldehyde), especially rare is still keeps its excellent impact strength in liquid nitrogen-196 ℃; Good drug resistance and corrosion resistance can compare favourably with polytetrafluoroethylene (PTFE), in certain temperature and concentration range, and anti-various corrosive liquids and organic solvent; Coefficient of friction low (its coefficient of kinetic friction is 0.1-0.22) is desirable self-lubricating material; Advantages such as fabulous noise reduction and avirulence, thereby worldwide extremely people's favor, its range of application is very extensive.
But, (reach 10 because the melting viscosity of UHMWPE is high
9Pa.S), mobile performance extreme difference (its melt index of melting body is almost nil).So, be difficult to directly melt extrude the spray silk, because there is great difficulty in the processing of UHMWPE, so, domestic and international technology and the equipment that also UHMWPE is not processed into silk at present.
